Septic System Installation

Septic System Installation in Annapolis

Anne Arundel County Installations from a Team with 70+ Years of Local History

At Shilling Septic Inc, we’ve been handling septic system installation in Annapolis and across Anne Arundel County since 1955. That’s more than 70 years of firsthand experience with the soil conditions, topography, and county permitting process that shape every project here. We’re locally owned and operated, and our knowledge of this region isn’t borrowed from a national playbook. It comes from generations of work on the ground.

We handle new construction installations, full system replacements, and septic tank replacement for residential and commercial properties throughout Annapolis. Site conditions here vary in ways that matter: soil permeability shifts across neighborhoods, seasonal groundwater levels affect drain field design, and properties near tidal waters face additional state requirements. Our team accounts for all of it before a single permit application goes in.

Site Evaluation & the Installation Process

Every septic system installation in Annapolis starts with a thorough site evaluation. We assess soil permeability, groundwater levels, lot size, and any local restrictions that affect system design and drain field placement. That assessment determines whether a conventional gravity system, mound system, pressure-dosed system, or alternative design is the right fit for the property.

Percolation testing establishes how quickly soil absorbs water and directly informs that decision. Properties within 1,000 feet of tidal waters fall under Maryland’s Chesapeake Bay Critical Area and are subject to additional Maryland Department of the Environment (MDE) requirements, including Best Available Technology (BAT) nitrogen-reducing units on new and replacement systems.

All new installations and replacements require a Septic System Construction Permit, reviewed by the Anne Arundel County Department of Health’s Sanitary Engineering Program. The application requires a site plan, soil test results, and a complete system design. We manage permitting coordination as part of the installation process, so property owners aren’t navigating county and state agencies on their own.

Annapolis Septic Regulations & the Bay Restoration Fund

Septic systems treat wastewater onsite, typically consisting of a septic tank and a soil absorption field (drain field). In Maryland, all system design and construction must comply with COMAR 26.04.02, with the Anne Arundel County Department of Health serving as the local approving authority for Annapolis properties. Local soil conditions and seasonal groundwater fluctuations in this area directly affect how systems perform and how they must be designed.

For properties in the Chesapeake Bay Critical Area, MDE-approved BAT nitrogen-reducing units are required on new and replacement systems. Anne Arundel County also administers the Bay Restoration Fund (BRF), a state-supported grant program that can fund replacement of conventional septic tanks with nitrogen-reducing units. Homeowners with combined household incomes up to $300,000 per year are generally eligible for coverage of 100 percent of the Maximum Allowable Cost, though new construction on previously vacant lots is subject to a reduction in the maximum grant amount. Eligibility is determined by the county; we can point you toward the right resources, but BRF determinations aren’t ours to make. For current permit fees, the county perc application fee is $450, and the nitrogen-reducing unit installation permit fee is $625.
